CollimationCircles
Collimation Circles, app for easy telescope collimation
This program was inspired by Mire De Collimation program written by Gilbert Grillot and Al's Collimation Aid. I combined best features of both and addes some of my own. Purpose of this program is not to reinvent the wheel, but rather to learn new technologies, become better at colimating my telescope and to learn something new. Main purpose of this program is to help you with aligning optical elements of your telescope such as secondary mirror, primary mirror, focuser, etc. Collimation Circles is developed with .NET 7 and AvaloniaUI Framework using MVVM architecture patern. Program was tested on Windows 10 and 11, Ununtu Linux 22.04.1 LTS (Wayland) and Raspberry PI OS Bullseye. I'm not able to test it on macOS, but it should work. Suggestions and contributions are welcome! -
